METHOD FOR PRODUCING HYPER-SOUND STREAM FOR AERODYNAMIC TESTS AND DEVICE FOR REALIZATION OF SAID METHOD (VARIANTS) Russian patent published in 2006 - IPC G01M9/02 

FIELD: experimental aerodynamics, possible use for researching characteristics of aircrafts.

SUBSTANCE: heating of working gas in closed space is performed by means of cauper gas heater, after which it is forced out at constant braking parameters through aerodynamic nozzle. Working gas comes from small multiplier cylinder. Device has pressure multiplier, cauper gas heater, launch device and aerodynamic nozzle. Cauper gas heater is mounted between pressure multiplier and launch device. In variants of device it can be provided with choke, mounted between cauper gas heater and launch device; valve and choke, serially mounted between pressure multiplier and cauper gas heater; valve and two chokes, while valve and one choke are mounted between pressure multiplier and cauper gas heater, and another choke is mounted between cauper heater and launching device.

EFFECT: increased source amount of working gas, more than tenfold, increased duration of working mode or working flow diameter, and also simplified construction of device and decreased pollution levels for working gas.
